+Important notice:
+
+Celery 3.0.8 fixes an issue with periodic tasks and timezones.
+
+If you are using the database periodic task scheduler
+then you have to reset the `last_run_at` fields
+to ensure that no invalid timezones are stored:
+
+.. code-block:: bash
+
+    $ python manage.py shell
+    >>> from djcelery.models import PeriodicTask
+    >>> PeriodicTask.objects.update(last_run_at=None)
